Re: Good strings for Rock/ Metal
Fender Super Bullets in 9-42 for my G&L guitars with the DF Vibrato. I believe the bullet end helps with tuning stability.
My Gibsons and Ibanez electrics get D'Addario XL in either 9-46 or 10-46, with the Ibanez guitars getting 9-42 (though this may change). The Music Man Sabres get 9-42.
I've got 16 acoustic dreadnaughts, and generally use D'Addario EXP or J-Series Phosphor Bronze, depending on usage. Most get mediums, one gets lights and two get their hybrid bluegrass gauge. The Tak 12-strings get the PB light EXP sets. I also have some Martin SP and SP Lifespan medium sets for my 6-string dreads and these are also high-quality strings. I HATE Elixirs...my Taylor sounds so much better with the D'Addario strings. And the D'Addarios have less tension, too!
I experimented with strings for many years before settling on the D'Addario, Martin and Fender strings. I like their quality and the D'Addarios are available everywhere. And using the standard 9-42 and 10-46, I'm usually able to get these sets cheaper than most of the odd gauge sets.
When it comes to keeping track of multiple guitars (I have 60!), standardization is a good thing. Even better, I'm getting excellent quality at good prices...not compromising at all.
